The default vb looks has one benefit in that it is easy to update and I want updates to be as hassle free as possible. Plus I like the way the post spans the entire width of the page.
Well this forum was always going to be light blue. I initially had it a much lighter shade of blue, but I changed it to this darker shade of blue, the other light blue looked too lame.

Pfft, easy to update. Updating is a sinch. I used to think it'd be hard, but even dramatically updating the style (like the Webmaster-Talk I did), most templates are still default.

vB uses a kind of 'fall through' template system. Say the forum looks for a template 'postbit', if it's been edited in the current style then it is returned, if not it returns the default (or parent) styles tempalte. You can think of a child template being on the first layer, and when the big vB "hand" comes down to grab a template, if it isn't there then it just goes down to the next "layer":

So the system see's no updated template in Custom, so it "goes through" and fetches the Default (parent) template.

Anyway, you probably already knew that but my point is, when you upgrade the default vB style is updated and thus, so is the majority of your style. You then just have to go into the thread at vb.com and search for updates to a template that _is_ edited, the most I've had to do with the DevBox style is update the 'logout' link to put in the userid.

So I think it's worth it, if you didn't get that message out of my babble

I did have an inclination as to how it worked, and how not all updates required custom modifications to the template, but nowhere near the level to which you explained. Gee you really know your vb stuff.
Actually long term, I will probably go with something similar to the style at devbox, that is main page with side column, but thread summary and actual post pages without the side column.

No I have no plans to sell this site at all. It is an important site of a strategic network.
And also I have a plan to capitalize on the sites, though that is way off in the future.
Cant see that happening for some time now.
I have had quite a few offers for computerforum.com but the answer is always NO, not for sale.
